Your excerpt is telling you what the issue happens to be.
You have multiple bad blocks on a disk drive or drives
and you can no longer write anything to those data blocks..

Use your service contract and open a support case.
Have technical support analyze the errors
and they will help you determine what hardware needs to be replaced.
Then you restore from backup, whatever data may need to be restored..

Well, it looks HDDs are OK. I will point those issues to the HBA or the connection between the Switch and the Storage (You 're using a SE 3510). If you have Oracle Support please log a Service Request. An Explorer file will help to do troubleshooting.

Please correct me if my understanding is correct or not from your last post. Are you saying that it is possible that the cause of the error messages is iffy cables or bad connections between the Server (Netra-T2000) and the StorEdge 3510? Thanks.
